Secured to the under face of the diskD is an arm D, (shown clearly in Figs. 1 and 5 of the drawings,) whichprojects beyond the projecting portion D 'of the disk and is adaptedateach rotary movement of .the disk D to contact with saidclutch-throwing yoke D whereby the machine may be thrown out of gear andthe apparatus caused to be at rest While the operator is inserting thearts to form the cover of a box upon one of t e heads K, by whichmechanism a posi; tive stop is afforded and rendering it possible forthe operator to start the machine by I thereof.

pressing the foot-lever C after the parts forming the cover have beenadjusted in place.

E designates a circular-outlined portion of the frame ofthe apparatus,(shown clearly in Fig. 4 of the drawings,) which forms a guide for thereciprocating posts F, which are shown in section in Fig. 4 of thedrawings and in elevation in Fi s. 1 to 3, inclusive E designates asecon circular portion of the frame which supports the upper ends of thevertrcally-reciprocating posts, and said two circu- 45 lar portions areheld together by means of bolts E having nuts u on the threaded endsReferringizo 6 of the drawings, an enlarged detail viewo one of saidreciproeating holding said posts' in an elevated Each of said postscarries a. pin

osition. 1n the nates an antifriction-wheel journaled upon said pinbetween the arms of the bifurcated end, while a secondantifriction-wheel F is mountedupon one end of said pin outside the endof the post, as shown clearly in the various views of the drawings. Inorder to actuate said posts longitudinally andverticall at the propertimes, I provide-a cam-trac G, upon which said antifrietion-wheel F isadapted to travel. A second cam-track (shown clearly in Fig. 2 of thedrawings and designated by letter G) is provided for the purpose ofcontacting with the antifrictionposts is illustrated with the means for.

wheel F at a predetermined moment to cause the posts to be positivelydriven to their lowest positions after the box-cover has been completed.Mounted in apertures in the circular portion E of the frame of theapparatus is a series of sleeves I, each of which of the drawings.)Mounted in each of said sleeves is a piston-stem I having a plunger I atthe bottom thereof and at the top a pin I, mounted in a bifurcated endof said stem, and I designates an antifriction wheel mounted upon saidpin I. A spring J is mounted upon each stem I one end of the springbearing against a shoulder J, formed on the inner face of said sleeve,while the other end of the spring bears against a shoulder I", formed onthe circumference of said stem I Said sleeve has a. cylindrical head 1and a spring I is interposed between a nut I, mounted upon a threadedportion of the sleeve and the under face of the circular section E ofthe frame and provided for the purpose of allowing the head and sleeveto yield lightly under pressure as a head K, which is fixed to the upperend of each of said posts F, is driven upward. The under surface of eachof said heads I is recessed out, as at I, sufficiently to receive theplunger I which latter when seated in said recess will have its lowerface flush with the lower edge of the head. Each of said heads K, whichare mounted upon the posts F, has a series of pins about its peripheryand risin from the upper face thereof provided for t e purpose ofholding the rim of a cover to receive a top or bottom, and fixed to eachhead K is an angle-iron K having a bracket K projecting therefrom, whichcarries a pin K, upon which a tilting bar K is mounted. The upper end ofeach of said bars K carries a pivotpin K, on which a clamping-shoe K ismounted.

Fixed to the top of the portion E of the frame is a series of plates 0,one of said plates being shown clearly in F ig. 8 of the drawings, andsaid plates are arranged so that their outer edges will form an octagon,and the inner edges of said plates form guides to allow the bars P tohave longitudinal reciprocating movements. Straps P are provided, whichserve to hold and guide the bars P in their is hollow and each beingheld upon the frame by means of a nut I. (Shown clearly in Fig. 7

movements, and which are secured to said disk B The outer end of each ofsaid bars P is formed into an elongated loop P (shown clearly in Figs. 8and 9' of the drawings,) and at the outer end of each of said loops is asetscrew P Projecting into each of said loops is a block P having aninclined edge P (Shown clearly in Fig. 6 of the drawings.)

Each of the posts F has an elongated slot F and a pin F is mounted inslot, and an antifriction-wheel F is journaled upon the pin F and isdesigned to the walls of said v contact with said block P when the bar Pis reciprocatedl The block P is provided for the purpose of cooperatingwith the antifriction-wheel F to support the post with, its head in anelevated position, while cooperating with the plunger I and the head Iin holding the parts of the cover together in the manner shown in Fig. 6of the drawings. It will be observed upon reference to Fig. 6 of thedrawings that the loop I, which is fastened to the end of the bar P,projects on either side of the post, and the set-screw P at the outerend of the loop is "adapted to form a stopagainst which the lower end ofthe tilting bar K is ada ted to contact for the purpose of holding theshoe K at the upper end of the bar in clamping relation with the meetingends of the band or flange of the cover during the rotary movement ofthe disks and of the circular ortions of the frame which rotate therewitIn orde'I to reciprocate the bars P, an antifrieti'on-wheel Q is mountedupon a pin Q, carried by each bar P, and is adapted to travel in thecam-groove B in the bottom of the disk B Said cam-groove is so formedthat the bar P will be driven out into the position shown in Fig. 6 ofthe drawings at a predetermined moment, whereby the shoe K, carried atthe upper end of the tilting bar K may be held against the band of thebox-cover during a partial rotary movement of the disk or wheel carryingsaid post.

Rising from the top of the frame is a post R, having an arm B projectingfrom the end thereof, and at the end of said armis a V- shaped cam Rwhich is positioned in the path of the antifriction-wheels 1*", whichare carried at the upper ends of the stems I and provided for thepurpose of causing the stem, with the plunger at the end thereof, to bedepressed in the position shown in Fig. 7 of the drawings, whereby acompleted top may be ejected from the head I.

The mechanism for receiving the cover when completed and as it isejected from the head I comprises the horizontally-reciproeating rack,rovided with the two rods L, (shown clear y in Fig. 16 of the drawings,)which rods are guided in the bearings L at the upper'ends of the bracesL (Shown clearly in Figs. 1 and 2 of the drawings.) A lever L ispivotally mounted on a pin L carried by the arms L and the upper end ofsaid lever L is bifurcated and is connected to a cross-piece of thereciprocating rack, as shown clearly in Figs. 1, 2, and 16 ofthedrawings. The lower end of said lever L is also bifurcated and carries apin M, which is pivotall connected to a rod M; Mounted upon a oss Mforming a part of the frame, is a pin 1 forming a pivot for the innerend of the arm M (shown in Fig. 16 of the drawings,) the outer end ofwhich arm has pivotal connection with the rod M, A drank-arm M isintegral with the arm M and carries a lug M, which is adapted totravel'in the camoove M in the member M (shown clearly 1n Fi 16 of thedrawings,) which is secured to a )oss projecting from the under surfaceof the disk B In the disassembled view of the parts of the I cover Ihave illustrated the band (designated by numeral 5) having its loweredge inwardly turned and the two disks 6 and 7, the former of which hasventilatin -perforations 8 and the spacing-blocks 10, w ich are placedupon 'K by the operator, the blocks. 10, coated with an adhesivematerial upon both faces thereof, first having been placed upon the upor surface of said disk, after which the and 5, which has beenpreviously turned into circular form, as illustrated in Fig. 18 of thedraw- .ings, and to the under flanged surface of which has been appliedan adhesive material, is placed upon the disk 7, and afterward the innerdisk 6 is placed upon the upper surface of theflange of the band 5, andby means of suitable adhesive material upon the upper surfaces of theblocks 10 the parts are in read iness to be compressed together by themechanism forming the subject-matter of the present invention. The partsbeing thus assembled, the machine is put in operation by the operatordepressing the lever C", which actu ates the clutch mechanism, and thedisks carrying the posts, each of which supports the parts to form acover, begin to rotate,and as an antifriction-wheel F carried at thelower end of one of the posts F, comes in contact with the inclinedportion g of the track G the post will be raised to the position shownin ICC Fig. 7 of the drawings, and in which position the head K willcause the parts of the cover to be held under heavy ressure against theunder surface of the p unger I and as the plunger and the sleevecarrying the same are allowed to yield slightly the jar incident to theupward throwof the post carrying the parts of the cover will be taken upby the spring I. As a post F reaches its highest position, which is ilustrated at the right ofFi 1 and in the detail view of Fig. 6, the barwhich passes through the particular post which has been raiseo will bethrown into the position shown in Fig. 6 of the drawings,and theset-screw 1'" at the end of the of said bar will contact with the lowerend 0 the tilting bar K and cause the shoe at the upper end of said barto clamp and hold the meeting and overlapping ends of the band of thecover securely together. The cover, with the plun- &

movements of the posts carrying the box-' covers are sufficiently slowtoallow the parts IO to adhere sufficiently by the time they are readyto be discharged after the machine has made a single cycle.- As one ofthe antifrice tion-wheels I comes in contact with the stationary cam Rthe stem I will cause the plunger I to be depressed into the'positionshown in Fig. 7 of the drawings, which will cause the cover to beejected from the machine. Immediatelybefore the plunger is depressed theantifriction-wheel F as it approaches the cam-track G will contact withthe under edge thereof and cause the .post to be lowered into theposition shown at the le of Fi 1 vMomentarily after the post has beendepressed to its lowest position the cam member M in its rotary movementwill cause the rods L to be driven forward underneath the cover, whichis held suspended by the plunger and head I of said sleeve in readi nessto receive the coverasit is ejected. The moment the cover is ejected thecam making a further rotary movement will cause the rack of which thebars L form a portion to be thrown outward with the cover thereon, andthe head of the post from whichthe completed cover has been removed isinreadiness to receive the parts to form a new top and the operation isrepeated. By the provision of the arm D which rotates with the disk D itwill be observed thatat each revolution of said disk said am willcontact with the clutch-throwing post D and the machine will be stoppedand in readiness to be started when the parts to form a cover are placedu on the head K by the simple compression '45 "0 the foot-lever C andthe-apparatus is under the ready control times. i

- While I have'shown ap'articular formof apparatus illustratinmymachirie for. Inaki of the operator at all tops forboxes, it wi beunderstood that Inlayvary the details of the same in various respects,if desired, without departing from the spirit of the invention.
